 We see that a FileWriter is created using the filepath of "RegionDefaults.outputCoulombRatePath" which is hard-coded to be "./coulombRates.txt." As seen by the "RegionDefaults.setCsepParams(...)" code listen above, this location is not overwritten by the CSEP generate input files. This indicates that the Coulomb Rates are not being correctly stored to the CSEP file system and are being overwritten with each subsequent run.

+RFC002 discusses the issues observed with the STEPCoulomb model in the CSEP New Zealand testing center. CSEP provides a computational infrastructure to perform and evaluate both prospective and retrospective earthquake forecasting experiments. In regards to a retrospective forecasting experiment, it was observed that the STEPCoulomb model installed in CSEP did not produce the expected output. This behavior was observed for the Darfield Experiment -- a retrospective forecasting experiment of the 2010 Christchurch Earthquake sequence addressing the information gained by including a physics-based component of the forecast.
 The STEPCoulomb model represents a hybrid model consisting of a statistical STEP model and a physics-based Coulomb stress model. The executable that computes the STEP forecast obtains a

 '''1. Overview'''
-It was suspected the STEPCoulomb forecast, computed by the New Zealand CSEP testing center, did not produce the expected outputs. This issue affects an on-going manuscript review, so an urgent response is needed. The problem was confirmed by comparing the STEP forecast with the supposed STEPCoulomb forecast and determining that there were no differences between the forecasts. Computing differences between the two forecasts indicated that both files were identical. It is expected that the physics-based Coulomb stress model should influence the rates forecasted by the statistical STEP model.

 Coulomb mask based on available slip models, and uses the information contained from the Coulomb stress model to provide physical constraints to the statistical STEP (short-term earthquake prediction)

 forecasting models.

 To implement this solution elegantly in CSEP we will register a new model that represents the true STEPCoulomb model. This model will use a separate executable containing the proposed solution outlined in this document. The CSEP system will treat the two models independently, and allow evaluations to be computed using the standard CSEP methodology.
